5.5.1 Compressed air for plasma and cooling gas.
5.5.2 Filtered compressed air free of oil and water
5.6 Plasma-cutting torch with central connector
EN - 14
NOTICE
• Precise adjustment of the compressed air pressure and flow/volume are
important for: igniting the pilot arc, quality of cut, service life of torch and
wear parts.
• An inlet pressure (p) smaller than specified results in thermal overload.
The correct torch inlet pressure must be ensured by proper adjustment of
the pressure monitor on the system side.
 Tab. 4 on page EN-5
NOTICE
• Use only compressed air which is free of dirt, oil and water.
• We recommend:
• Initial filter 5µm of retained particle size
• Submicro filter 0.01 µm of retained particle size
• 99.99% of oil separation rate
• Air throughput for PSB 31 at least 4.5bar: >160 l/min
Air throughput for PSB 60 at least 6.0bar: >180 l/min
Air throughput for PSB 121 at least 6.0bar: >180 l/min

NOTICE
• The plasma-cutting torches with central connector must only be
connected to power sources with central sockets which comply with the
safety requirements according to EN 60974-1 and EN 60974-7.
• The assignment of the cutting torch and cutting power source is clearly
defined by the coding on the plug and socket and must be observed
under all circumstances.
